Chinese Journal of Postgraduates of Medicine 2009;32(z2):52-53
Objective To explore the significances of the endoscopic diagnosis for chronic atrophic and histological assessment gastritis (CAG). Method Five hundred patients with CAG were determined by gastroscopy and the samples of gastric mucosa were examined by the pathology. Results Among 500 cases of CAG by gastroscopy, 429 cases were similar with the pathologic results and the coincidence rate of diagnosis with endoscopy and pathology was 85.8%(429/500), 370 cases had a change of atrophic gastritis in cirumjacent mucosa. Conclusion The coincidence rate of diagnosis under endoscopy and pathology is quite good in CAG.

Objective:To investigate the relation between eotaxin, STAT6 and allergic rhinitis through comparing expressions of eotaxin and STAT6 in nasal mucosa of normal guinea pigs and of guinea pig allergic rhinitis models. Methods: Twenty-four healthy guinea pigs were equally randomized into 2 groups: normal control and allergic rhinitis models. Guinea pig allergic rhinitis models were established by the ovalbumin challenge method. Protein expressions of eotaxin and STAT6 in the nasal mucosa of the 2 groups were detected by immunohistochemical technique. Results: Expressions of eotaxin and STAT6 were found in the nasal mucosa of both normal guinea pigs and allergic rhinitis guinea pigs. Eotaxin was mostly located in the cytoplasm of the serous and mucous glands,while STAT6 mostly in the cytoplasm of subepithelial infiltrative cells.Expressions of eotaxin and STAT6 in the nasal mucosa of allergic rhinitis guinea pigs were significantly higher than those of normal guinea pigs~(P

Objective To assess the patterns oflinkage disequilibrium (LD ) of16 STR loci on X chrom o-som e and investigate the genetic stability. Methods G enom ic DNA samples extracted from blood stains from 500 unrelated individuals and 885 lineage m em bers from E astern C hinese H an population were genotyped through m ultiplex am plification using ID typerX-16 kit by our independent research followed by capillary electrophoresis. LD was assessed by PowerM arker v3.25 software and m utation rate of every locus was analyzed. Results LD were not found at the 16 X-STR loci. A llele m utations were observed at 10 loci. A m ong them , m utation rates of DXS6809 and DXS7132 were both up to 0.004 8. Conclusion W hen the 16 X-ST R loci included in ID typerX-16 kit were used for parentage testing, product princi-ples can be applied to calculate the likelihood, but m utation should be taken into consideration in the case that the genotypes do not m eet the genetic law(especially at DXS6809 and DXS7132).

Objective To investigate the population genetic polymorphisms of 24 Y-STR loci in unrelat-ed individuals in Eastern Chinese Han population, and to compare the difference of Han group between Eastern China and Guangdong.Methods The population genetics of 24 Y-STR loci in 268 unrelated Han individuals from Eastern China were analyzed by GFS 24 Y-STR amplification kit. The allele fre-quencies in Eastern Chinese Han population were compared with the data in Guangdong Han population, and the difference analysis between two groups was performed.Results Among the 24 Y-STR loci of 268 unrelated Han individuals from Eastern China, 235 alleles and 267 haplotypes were observed. GD value ranged from 0.5649 to 0.9668. The difference between 12 loci(DYS622,DYS552,DYS443etal.) of Han population in Eastern China and in Guangdong was statistically significance.Conclusion GFS 24Y STR amplification system shows favorable polymorphisms, which can be used in patrilineal genetic relationship identification.

Objective To investigate the relationship between hepatic fibrosis stage and clinical serum fibrosis markers in patients with chronic hepatitis B (CHB).Methods Liver puncture biopsy was performed in 189 CHB patients.The serum levels of hyalyronic acid (HA),laminin (LN),procollagen Ⅲ (PCⅢ),collagen Ⅳ (Ⅳ C),liver function and peripheral blood routine were detected simultaneously. The comparison, correlation and regression analysis were performed based on different fibrosis stages (S).Results From SO to S4 group,levels of PC Ⅲ,γ-glutamyl transpeptidase (γ-G-T),total bilirubin (TBil),protein electrophoresis γ-globulin (Ely-γ) and prothrombin time (PT) were progressively elevated,the differences were statistically significant (F value was 3.325,6.218,2.958,10.160 and 7.028,P<0.05),while cholinesterase (CHE),total protein (TP),albumin (Alb) and platelet (PLT) were progressively declined,the differences were also statistically significant (F value was 15.984,3.768,14.919 and 4.737,P<0.05).The differences of LN,IVC,ALT and AST between groups were statistically significant (F value was 4.618,2.795,2.649 and 3.199,P<0.05).Fibrosis stages (s) was positively correlated with LN,PCIII,ALT,AST,TBil,γ-GT,Ep-γand PT (r=0.200,0.306,0.172,0.273,0.153,0.402,0.415,0.269,respectively);while it was negatively correlated with CHE,TP,Alb and PLT (r=-0.502,-0.208,-0.413,-0.390,respectively);I.N,AI.T,CHE,PLT and Ep-γ were the independent risk factors which affecting hepatic fibrosis stages.Conclusions Liver fibrosis stage in histopathology was correlative in certain degree with the serum markers of hepatic fibrosis,liver function,and blood routine examination.Combined analysis of clinical data may be used to early diagnose hepatic fibrosis non-invasively.

Objective To investigate the clinical characteristics and imaging manifestations of AIDS complicated with disseminated Penicillium marneffei (PM) infection. Methods A total of 12 patients with AIDS complicated with disseminated PM infection were collected and the symptoms, signs, laboratory examination results and image manifestations of these patients were analyzed retrospectively. Results (1) The diagnosis of PM infection in all the 12 cases were confirmed by peripheral blood culture.All the 12 cases (100%) had irregular fever (38-41 ℃) and enlarged lymph nodes, 8 cases (66%) had skin rashes; 8 cases (66%) had hepatomegaly; 9 cases (75%) had splenomegaly while 8 cases (66%) had anemia. (2) Imaging manifestation: Five cases manifested bilateral pulmonary disseminated miliary nodular shadows or lattice signs; 1 case showed enlarged hilar lymph node and 2 zases showed patchy shadow with pleuritis. One case presented sub-pleural curve line shadow at the posterior part of the right lower lung,and adhesion between the intestinal wall and intestinal mesentery in mass form in the abdomen by CT examination. Conclusion Patients suffering from AIDS (CD4T lymphocytes <50/μ L) with impaired immunity might be susceptible to complication of disseminated PM infection, which presents mainly damage of multiple organs and symptoms such as fever; enlargement of liver,spleen and lymph nodes, as well as specific skin maculopapular rashes. Imaging manifestations in the lungs were revealed as miliary nodular shadows and lattice-like shadows. Intensified abdominal CT might reveal presence of several enlarged postperitoneal lymph nodes and intestinal adhesion in shape of cakes.

Pulmonary hemorrhage is a common critical disease in neonates, with high mortality. Early and accurate diagnosis is the key to successful treatment. Recently, lung ultrasound has been successfully used to diagnose neonatal pulmonary hemorrhage. Main ultrasonographic manifestations of neonatal pulmonary hemorrhage are described in this article, including shred sign, lung consolidation with air bronchogram, pleural effusion, lung edema, pleural line abnormality and A-line disappearance.
